Abstract (en)
An engine control system generates (30) a manifold pressure demand signal from an engine output demand signal provided by an accelerator pedal position transducer (25) or a cruise control. The manifold pressure demand signal is compared (42) with the actual inlet manifold pressure (43) and the difference used to control (39, 44) an engine throttle (7) and a turbocharger (11, 12) by means of a waste gate (13). <IMAGE>
